My hair actually feels thicker!

I have super thin fine shoulder length hair and it feels and looks thicker when I use this treatment! It doesn’t weigh my hair down and it’s super soft! I use all of the R&Co thickening products and love them!!!!

Fine and Thin hair

So far I like it. I have very thin fine hair and it seems to curl nicely when I curl it. But what I most like is that my scalp has cleared up! Other shampoos and rinses cause my scalp to break out and itch! But R+Co seems to not cause that, so time will tell. So far So good!

Thickening is what it is!

If you have thin hair! You won’t after using this treatment conditioner .

Every 7 days for 10 minutes.

That’s all it takes!
